Washington -LRB- CNN -RRB- -- Jeb Bush might not be announcing his candidacy for president in 2016 any time soon , but he is sharing his vision of the future with Iowan Republicans .

The Des Moines Register reports Tuesday that GOP Iowans recently received mailers from the former Floridian governor that sounded more like a campaign pitch than a donation plea for his social fundraising group , Excellence in Education National .

In the four and a half page letter , Bush proposes an economic plan that he believes are the stepping stones to make the country `` the most economically and socially mobile country in the world , '' once again .

`` I am gravely concerned about the direction of our country , the lack of leadership in Washington , and the economic stagnation we have suffered through for the past six years , '' he said in the beginning of his letter .

Kristy Campbell , Bush 's spokeswoman , confirmed to CNN that the letter was sent in an effort to raise awareness about the current state of the education system , which should not be interpreted as a political sign .

`` Gov. Bush raises money for his education work throughout the year and the letter is not related to any decision about his political future , '' she said .

Campbell said that the governor will consider running and expects to make a decision later this year or in early 2015 .

The Des Moines Register said that Iowans had told them that they had never received anything from Bush or his foundation before . However , Campbell said the mailers are being sent across the country , not just to Iowa Republicans .

In several bullet points , Bush lists the need for immigration reform , simplifying tax regulations , and other policies , half a page before touching upon the `` failing education system . ''

While the mailer does ask Iowans to donate for his cause , Bush 's disclosure of his vision for only adds fuel to the rumor mill about whether he will run in 2016 .
